Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3318, here are decompositions:

5 + 3313 = 3318
11 + 3307 = 3318
17 + 3301 = 3318
19 + 3299 = 3318
47 + 3271 = 3318
59 + 3259 = 3318
61 + 3257 = 3318
67 + 3251 = 3318

Showing the first eight; more decompositions exist.
